2. Application of imported Mitsubishi MBR membrane module HD-300-LY

 1. Example of flow chart of imported Mitsubishi MBR membrane for wastewater treatment:

  Raw water → grille → original pool → anaerobic pool → aerobic pool (MBR membrane pool) → treatment pool → water discharge

 2. Example of flow chart of imported Mitsubishi MBR membrane for reclaimed water reuse:

  Raw water → grille → conditioning tank → facultative oxygen tank → aerobic tank (MBR membrane tank) → sodium hypochlorite disinfection → recovered water

  The effluent treated by MBR can be directly treated with RO membrane to achieve the water quality from tap water to pure water and ultra-pure water. With this technology, it is possible to reuse domestic sewage and industrial waste water into industrial water after treatment.

 3. Example of flow chart of imported Mitsubishi MBR membrane for seawater desalination pretreatment:

  Sand filter → primary filtration → secondary filtration → conditioning tank → sterilization tank → membrane separation tank → conditioning tank

   In the past, flocculants were generally used for pretreatment. After using this product, the process of adding flocculants can be omitted, which not only saves costs, but also greatly reduces the load of RO membrane desalination and extends the life of the entire system.

3. Introduction to the cleaning method of imported Mitsubishi MBR membrane module HD-300-LY

   Membrane cleaning generally uses sodium hypochlorite, oxalic acid, citric acid, hydrochloric acid, sulfuric acid and other drugs

 1. The imported Mitsubishi MBR membrane module itself has a self-cleaning mode

   The membrane module runs for 7 minutes and stops for 1 minute for self-cleaning without backwashing

 2. Imported Mitsubishi MBR membrane maintenance and cleaning

   One time/1 week is the standard. NaOCl with an effective chlorine concentration of 300 ppm to 500 ppm is quantitatively passed from the secondary side for 15 to 30 minutes. The amount of chemical solution is 2L/m2 per unit membrane area + the capacity of the introduction piping. During implementation, stop aeration. This operation basically runs automatically.

 3. Imported Mitsubishi MBR membrane to resume cleaning

  Recovery cleaning is carried out every 3 months or when the suction pressure exceeds the set value (= when the pressure difference between the membranes rises). The purpose is to clear the blockage of the membrane and restore the pressure difference between the membranes to the initial value.

 4. Imported Mitsubishi MBR membrane immersion cleaning (offline cleaning)

   When the recovery cleaning cannot restore the pressure difference between the membranes, or when sludge is attached between the membranes due to the failure of the machinery and equipment, immerse the entire membrane module in the chemical cleaning tank to remove the blockages. The purpose is to restore the pressure difference between the membranes to the initial stage. The status of the value. The cleaning effect of immersion cleaning is better than that of recovery cleaning.
